Moving Toward a Holistic Conceptual Framework for Understanding Healthy Aging Among Gay Men

In the last four decades, we have witnessed vast and important transitions in the social, economic, political, and health contexts of the lived experiences of gay men in the United States. This dynamic period, as evidenced most prominently by the transition of the gay rights movement to a civil rights movement, has shifted the exploration of gay men’s health from one focusing primarily on HIV/AIDS into a mainstream consideration of the overall health and wellbeing of gay men. Against this backdrop, aging gay men in the United States constitute a growing population, for whom further investigations of health states and health-related disparities are warranted. In order to advance our understanding of the health and wellbeing of aging gay men, we outline here a multilevel, ecosocial conceptual framework that integrates salient environmental, social, psychosocial, and sociodeomgraphic factors into sets of macro-, meso-, and micro-level constructs that can be applied to comprehensively study health states and health care utilization in older gay men.     

THE EFFECTS OF VARIABLE AND FIXED TRANSACTION COSTS ON OPTIMAL INVESTMENT DECISIONS

This paper studies the impact of variable and fixed transaction costs on investment decisions under conditions of risk. The decision model is first formulated as a mixed-integer nonlinear program. The following subjects are then examined: the structure of the investment frontier facing the investor and the effects of transaction costs on this frontier, the impact of transaction costs on the investor's optimal investment strategy, and the conditions for the equilibrium structure of risky asset prices and risk-return relationships. The main finding is that the relaxation of the assumption of the absence of transaction costs eliminates some of the most unattractive implications of the classic capital asset pricing model (CAPM) while preserving the more attractive implications of this model. Also, our model provides explanations for some discrepancies between the theoretical CAPM and empirical findings and, therefore, is a step toward narrowing the gap between theory and practice.     

Quantifying fear: The social impact of terrorism

This paper proposes a methodology to measure social impact of terrorism. We define a multidimensional terrorism index based not only on deaths but also on other variables such as injuries, bombs and kidnappings. The weight of each terrorist activity is given by its social impact, which is estimated through its relevance in the media. For this task we build up a new data set from the four most important newspapers in Spain, namely, El País, El Mundo, ABC, and La Vanguardia. Finally, we evaluate the social impact of ETA terrorism in Spain from 1993 through 2004.     

Client acceptance decisions of Dutch auditing partners

A vignette study of 567 client acceptance decisions by 67 Dutch auditors showed that the prospect of acquiring additional assignments significantly increases the likelihood that auditing partners accept an audit assignment from a new client, thereby violating a rule of the auditing profession. Audit firm strategy was found to moderate the effect of the acquisition of additional assignments: partners working in audit firms emphasizing a professional orientation are less likely to accept such risky assignments, whereas a commercial orientation of audit firms was found to exacerbate the effect of acquiring additional services. Contrary to expectations, punishment severity for professional mistakes increases the likelihood of client acceptance.

Metabolic and hormonal responses to different resistance training systems in elderly men

Objective: To compare acute and sub-acute responses in hormonal profile and metabolic parameters in elderly people who participated in two methods of strength training (ST) with equalized loads.

Methods and materials: A total of 12 elder individuals (65?±?3 years) were randomly assigned to two training methods: constant intensity (CI, 3 sets of 10 repetitions with 75% of 1RM) and variable intensity (VI, 1st set: 12 repetitions at 67% of 1RM?>?2nd set: 10 repetitions at 75% of 1RM and 3rd set: 8 repetitions at 80% of 1RM). Both methods included the following exercises: leg press, knee extension, and squat with 1?min rest intervals between sets. Free speed of execution and maximum range of movement were encouraged throughout each set for both protocols. Blood samples were analyzed included glucose, testosterone (T), cortisol (C), T/C rate, growth hormone (GH), and lactate at 2 and 24?h post intervention.

Results: There were no observed differences in glucose, testosterone, GH, and lactate concentrations both at 2 and 24?h after the execution of the two training methods. However, significant increases in the levels of T/C rate and decrease on cortisol were observed immediately post exercise for both protocols.

Conclusions: Although no significant differences were observed between the two interventions in relation to the hormonal and metabolic parameters analyzed, both training methods promoted a favorable response, with a slight superiority noted for the CI method relative to the hormonal profile.     

How Good Are Networks for Migrant Job Seekers? Ethnographic Evidence from North Carolina Farm Labor* Camps

Migrant farmworker networks are vital components in their job seeking and underemployment minimization strategies. Yet, farmworker cultural, physical, and institutional isolation along with the itinerant and clandestine features of farmwork have become major obstacles in the development of robust lateral communitywide network ties that would otherwise favor reciprocity and resource sharing. Thus, contrary to the positive social capital assumption, we argue that the paucity and fragmented features of farmworkers’ lateral ties have increased their vulnerability and locked them in exploitative relationships in a hostile social environment that makes impractical or impossible the formation of alternative ties. Our study is based on participant observation through a 6‐week stay in three North Carolina farm labor camps. On‐site evidence shows that the two larger groups of solitary male farmworkers and farmworking families break up into smaller groups, each group in pursuit of its own short‐term goals. We conclude that, even though farmworker networks help them to find and ensure temporary jobs, their inability to use the networks to share resources is ultimately detrimental for participants’ long‐term socioeconomic prospects.

School Meals and Food Poverty: Children’s Views,Parents’ Perspectives and the Role of School

This paper addresses the importance of school meals in balancing food budgets and diets among 45 low‐income families in Portugal. Drawing on interviews with both parents and children (aged 11–15 years) we found that children’s views on the quality of school meals affect their willingness to eat at school and heighten parental concerns with health, food and resources. For parents, school meals are crucial to ensure children’s dietary variety and balancing tight food budgets. Schools’ role in food poverty alleviation is also critically addressed, contributing to current and future sociological studies of children, school meals and food poverty.     

Top Managers' cognition facilitates organisational ambidexterity: The mediating role of cognitive processes

It is empirically founded and tested that top management team group processes facilitate ambidexterity, whereas the role of top managers' cognition has remained empirically largely neglected. This study contributes to the literature of top managers' cognition by theoretically developing the relationship between cognitive frames and organisational ambidexterity, and the mediating process of cognitive differentiation and integration. The study empirically tests the proposed model in cross-sectional design by employing a sample of 101 top managers, using partial least squares structural equation modelling.The study shows that top managers' paradoxical frames encourage the engagement in cognitive differentiation and integration, whereas top managers' paradoxical frames are not significantly related to organisational ambidexterity. Solely appreciating exploitation and exploration does not foster ambidexterity, but is an antecedent for top managers' cognitive differentiation and integration. Top managers' cognitive differentiation and integration mediate the relationship between top managers' paradoxical frames and organisational ambidexterity. Additionally, top managers' cognitive integration moderates the effect between top managers' cognitive differentiation and organisational ambidexterity, which stresses the pivotal role of top managers' cognitive integration.
